Hand Vacuum Pump, without Gauge
Each squeeze of the pump delivers approximately 15ml, and can be used to create vacuum of 50mm Hg, or air pressure of about 2 atm (standard atmosphere). Pump features a removable cap and elastic valve to provide quick vacuum release without dismantling the pump from the line. Recommended for general laboratory use for applications that do not require high or precise vacuums.
